ABSTRACT:
A combustion-engined setting tool (10) for driving fastening elements in a workpiece includes a combustion chamber (11), a drive piston (15) displaceable in a piston guide (17) and driven by expanding gases produced in the combustion chamber (11), and a device for returning the drive piston (15) in its initial position as a result of pressure difference between chambers formed on opposite axial sides of the piston head (115), and including a pump (20).
